The problem
Intervention: Social and Emotional Learning-based drug abuse prevention program with culturally tailored, developmentally appropriate curricula for lower and upper elementary students
Who it was tested with: 194 elementary school children in Korea; 99 upper elementary students completed pre-post measures.
The same group is measured before the intervention and again afterwards, with a baseline and an endline and sometimes a midline. Change is visible, but other causes cannot be ruled out.
"For upper elementary students (n=99), pre-post measures of self-esteem and attitudes toward drug abuse were also analyzed." The study measured outcomes before and after the intervention in the same group without a comparison group, meeting the definition of a pre-post design, though the lack of statistical significance makes the evidence inconclusive about program effectiveness.
No control or comparison group; small sample size; single school setting; effect sizes were small; lack of statistical significance limits ability to conclude program effectiveness
